This invention relates to farm Cultivators for cultivating corn or other field crops, and one of the objects of the invention is to provide practicabl and convenient means for controlling and regulating the depth oi the cultivating, since con ventional forms of cultivators are not suited nor adapted to such uses.

Another object of the invention is to provide a spring toothed cultivator with means and structural features incorporated therein for setting the machine to any job which it can be adapted to do, or in other words for setting it for use on a high bed, or on water furrows, oron a low bed or for ground level work.

Still another object ofthe invention is to provide for incorporation upon any conventional form :of spring toothed cultivator or the like,the same including agang of cultivator blades rearwardly mounted upon a main beam, a set :of adj ustable connections for connectingthemain beam to a forwardly disposed tongue'orwork beam, said connections including a pair of relatively straight links for adjustably joining the forward end of the main beam to the rear end of the tongue or work beam, and two pairs of arcuate overhead links, one of these pairs being secured at their rear ends to each side of the forward end of the main beam with their free ends extended forwardly in alignment, and the other pair being secured at their forward ends to each side of the rear end of the tongue or work beam and extended rearwardly in alignment and overlapping relation at the sides of the first mentioned pair of links, the overlapping ends of the two pairs of links being pierced with transversely aligned pairs of holes for receiving an adjustment bolt adapted to be passed through any selected and transversely aligned set of holes, for raising or lowering the frontal tongue or work beam relative to the rearwardly disposed main beam, for causing the cultivator to work corresponding deep or shallow.

With the stated objects in view, a preferred embodiment of the invention is shown in the drawing, wherein:

Figure 1 is a side elevation of an assembly including the forward end of the main beam of a cultivator as connected with the rear end of a tongue or work beam by means of the elements comprising my invention.

Figure 2 is a top plan view of the assembly shown in Figure 1.

Figure 3 is a side elevation of a spring toothed cultivator shown as adjustably connected to the rear end of a tongue by means of the elements comprising my invention.

'2 Claims. (Cl. 97 199) Figure 4 is a top plan view of the assemblyshownin Figurei'l.

The invention is designed for adjustably con-- necting' a conventional form of spring toothed cultivator, such as represented generally at A and which includes "a main beam I, to a forwardly disposed tongue or workbeam representedat la, the latter being spaced as indicated at 2 in operative alignment with the beam l' and con=- nected to the clevis 3 thereof by means of the relatively straight pair of links 4-whicha'ie bolted in transverse alignment at each side of the rear end of the tongue or work beam in and extended rearwardly' at each side of the clevis 3,

a to which clevis the links are pivotally joined by means of a bolt *5 passedthrough the rear ends of the links and through any selected hole of ward'lyofthe elevis 3, the :lree ends iof these linksbeing extendedforwardly in an upwardly spacedrelation 'over the 'cl'evis, as clearly shown in Fig ures 1 and 3. A similar pair of arcuate overhead links 8 are similarly bolted as indicated at 9 at their forward ends to the sides of the rear end of the tongue or work beam la, and since only one bolt 9 is employed for this connection, these links are thus pivotally connected with the beam la. The free ends of the links 8 are extended rearwardly in outwardly overlapping relation at the sides of the rear links 6, as shown in Figures 1 and 3. The overlapping ends of the links 5 and 8 are pierced with a series of transversely aligned bolt holes as represented at (in and 8a respectively adapted to releasably engage a connecting bolt 10, whereby these links may be adjustably joined together at their meeting ends by passing the bolt I0 through any selected set of the holes.

A conventional pair of laterally spaced cultivator handles H are bolted at their forward ends to the rear portion of the beam I as shown, and these handles extend rearwardly and upwardly in a transversely flared arrangement as shown, being braced apart in this relation by means of the braces l2 and [3. The usual V-shaped frame I4 is bolted to the under side of the forward end of the beam I with flared ends disposed rearwardly as shown, this frame carrying the customary series of spring teeth Ma depended from the frame at each side thereof. This frame is braced at its rear ends by the cross brace Mb. The usual 3 double tree I5 is adjustably connected with the tongue or work beam I, by means of the clevis 16 which is supported in place by a bolt ifia passed through the forked ends of the clevis and through any selected one of a series of holes I! formed through the tongue. Clevises and lap ring uni ts l8 are provided at the ends of the double tree for attaching single trees at each side of the tongue in the usual manner for hitching a team to the implement. The cross brace l3 includes uprights l3a at each side pierced with series of transversely aligned bolt holes I31), and whereby the handles ll may be adjusted as to height by means of bolts l3c passed through the handles and selected holes l3b as selected for the purpose.

In use and for level ground working or culti-' lowered angularly relative to the beam 1, thus causing the teeth [4a to turn upwardly to a greater degree, and to penetrate the ground to a less degree. These adjustments of the tongue and beam are readily made by merely removing the bolt II) which tie the links 6 and 8 together, and

then resetting these links as desired and re-inserting the bolt in place through the links.

While I have here shown and described a certain embodiment of the invention, and specific structural features thereof, the assembly as shown may be changed or modified in various details as desired, within the scope however of the appended claims.

Iclaim: 1. In a cultivator having a main beam and a separate tongue or work-beam positioned forwardly thereof in longitudinal alignment therewith and pivotally connected therewith for vertical movement, means for vertically and angularly adjusting the tongue or work beam relative to the main beam, said means including two pairs of arcuate overhead links, one of said pairs being secured at their rear ends to each side of the forward end of the main beam with their free ends extended upwardly and forwardly in transverse alignment, and the other pair being secured at their forward ends to each side of the rear end of the tongue or work-beam with their free ends extended upwardly and rearwardly in overlapping relation across the free ends of the first named pair of links, and means for releasabll' and adjustably locking the overlapped ends of the links together at any set position of adjustment.

2. In a device according to claim 1, the said pivotal connections between the ends of the main beam and the tongue or work-beam comprising a pair of clevis links secured in transverse alignment to the opposite sides of the forward end of the main beam and extended forwardly, the said clevis links being formed with series of vertically spaced and transversely aligned adjustment holes, a pair of relatively straight links bolted in transverse alignment at each side of the rear end of the tongue or work-beam and formed at their extended rear ends with transversely aligned holes whereby the clevis links and straight links may be adjustably connected by means of a bolt passed through selected aligned holes of the clevis links and through the holes of the straight links.
